Is this really even true?  Surely ethtool supports people who rename
their ethX interfaces to something else, even ibX?  For example on my
system I can do the following:

    # ip link set eth1 name ib5
    # ethtool ib5
    Settings for ib5:
            Supported ports: [ TP ]
            Supported link modes:   10baseT/Half 10baseT/Full
                                    100baseT/Half 100baseT/Full
                                    1000baseT/Full

                                    1000baseT/Full

So what's the problem exactly?
